Specification of Letterstlfatent. I Pat-911 5661 NOV. 29, 1921- Application filed January 19, 1920. Serial No. 352,418.

T 0 all to item it may concern Be it known that I, NASYL Home. citizen of Ukraine, residing at lfinnipeg, 1n the 'Province of Manitoba and Dominion of Ayfurther object of the invention is to.

provide a padlock embodying a hi1 l shackle and a tensione'd sliding bolt with a screw carried by the bolt and adapted to be shifted within the lock casing to move the same to engaging and disengaging sitions relative to the shackle keeper.

lVith the above and other objects in view, the invention consists in the novel form, combination and arrangement of parts here in fully described and shown in the aecoropanying drawing, wherein like reference characters indicate similar parts throughout the several views.

In the drawing, v Figure 1 is a side elevational view of a padlock constructed in accordance with the present invention,

Fig. 2 is an end elevational view of the lock,

Fig. 3.,is an end elevational view taken from the opposite end of the lock,

Fig. 4 is a vertical longitudinal sectional view of the lock showing the tensioned sliding bolt'with the bolt in locked position, I

Fig. 5 is a sectional view similar to Fig. 4: showing the sliding boltretracted with the shackle removed from the casing,

Fig. 6 includes side and end elevational views of the sliding bolt removed from the casing and Fig. 7 is a side elevational key for the lock.

Briefly described, the present invention aims to provide a padlock wherein a pivview of the oted shackle has the keeper end thereof securely locked within a casing with a special form of key cooperating with the sliding 2 the shackle keeper to bolt in the lock for shifting the bolt to dis en aging position relative to the shackle keeper. tural standpoint the casing having a shackle pivoted thereto with a tensioned bolt slid able within the casing and adapted for err-- gagement with the keeper end oi the shackle. Anscrew forms a part of the sliding bolt and is adapted to be enga ed by, a threaded key. for shifting the bolt within the casing to free the same from an gil' ctgfiment with-the shackle keeper. r

Referring more in detail t'othe acconr jpanying drawing, there is illustrateda padlock embodying a casing 8 having an enlarged end 8 defining annular shoulder 8 carrying spaced lugs 9 betweenwhich a shackle 10 pivoted upon the pin 11, the casing 8 havinga sideopening 12 adjacent the closed end .13 thereof through which; the keeper 10 oftheshackle is adapted to be projected. The inner edgev wall or the shackle 10 is provided with a shoulder 19 and an offset portion 10" so that the shackle in effect, interlocks with the casing by the engaging shoulders 8 and 10 as shown in Figs. 1 and 2. This construction removes considerable strain from the shackle pivot 11 when the shackle-is subjected to. end thrusts. i

The sliding bolt for retaining the shackle- The lock embodies from a strue.

keeper 10 within the casing 8 embodies a disk portion 1% insertible within the open end of the casing as SllOWIl'lILFlQIf-S. 4t and awhile the pin 15 carried by the forward face of the bolt body 1 1 is adapted to be projected through the opening 16. in the partition 17 extending transversely of the casing, the opening 16 being arranged ad jacent the casing opening 8 as shown in said figures. The rear face of the bolt body l lcarries a screw 18 bywhich Qsaid bolt is shifted within the casing. After position ing the bolt within the casing, the co1npres sion coil spring 19 is placed therein to surround the screw 18 of the sliding bolt, the

inner end of the spring engaging the rear.

face of the bolt body 14: while said spring at its rear end is engaged by the ringQO that is sweated or otherwise secured inthe open enlarged end 8 of the casing.

lVith the construction above described, assuming thatthe shackle keeper 10 is within the casing 8 as shown in Fig. 4, the spring 19 forces the bolt body forwardlyv i into engagement with the casing partition 17 for projecting the bolt pin 15 through the V partition opening 16 and into the shackle keeper The shackle keeper thus positioned, is securely maintalned 1n locked ar- 7 rangement, and in order to release the shackle from the casing, the form of key 21 shown in Figs. 5 and 7 is employed. The key'21 has a shoulder portion 22 carrying a handle 23 while the body portion lei thereof is of tubular construction and internally threaded as at 24:. The key" 21 is inserted within the open end of the lock casing 8 for engagement with the screw 18 and by threading the key onto the screw,

the shoulder22 of the key will engage the enlarged end 8 of the casing and cause the screw 18 upon the sliding bolt 14 to be retracted into the tubular key 21 with the sub sequent withdrawal ofthe bolt pin 15 from the shackle keeper 10, With the bolt and bolt pin retracted, the; shackle 10 may be moved upon its pivot pin 11 with thekey 21 positioned within the casing. When it is desired to lock the shackle within the casing, the keeper 10 is moved within the opening 12 of the casing and a key reversely rotated to cause a forward projection ofthe boltywith the bolt pin 15 received lin the shackle keeper 10'. Rotary movement of the bolt is prevented by the bolt pin 15" projecting through the partition opening minor changes may be made in the form;

combination and arrangement of parts witlr out departing from the spiritand scope of the inventlon as hereinafter claimed:

What is claimed as new 1s:

A lock of the class described comprisinga circular casing having an enlarged rear end defining a beveled. annularflshoulder, spaced lugs-formed on and extending lat erally from the enlarged rear end of said casing, a shackle having one end pivoter between said lugs with an inner edge thereof oiiset tov provide a beveled shoulder for engagement with the beveled casing shoulder compensating for strains when the shackle is subjected to end thrusts, a keeper portion upon the oifset end of said shackle projecting into the casing, and a sliding bolt within the casing adapted to engage the shackle keeper] tureu WASYL KUC.
